“Logic-Based Causal Discovery for Heterogeneous Datasets”
Abstract: Computational Causal Discovery aims to induce causal models, causal networks, and causal relations from observational data without performing or by performing only few interventions (perbutations, manipulations) of a system. A relatively recent approach to causal discovery, which we call logic-based integrative causal discovery, will be presented. This approach accepts and reasons with multiple heterogeneous datasets that are obtained under different sampling criteria, different experimental conditions (perbubations, interventions), and measuring different quantities (variables). Applications to business data will be discussed. In addition, current complementary research directions in our lab will be presented, including scaling up to Big Data, learning of mechanistic causal models, the MXM R package capabilities and others.
